First Claim
Patent Images
1. An ultrasonic monitor for measuring pulse rate values in a living subject, comprising:
- a) at least one source of ultrasonic energy;
b) a gel pad comprised of a polymer and from about 50 to about 95% by weight of an ultrasound conductive diluent, wherein said polymer is characterized by having i) needle penetration from about 5 to about 300 ({fraction (1/10)} mm) according to ASTM D15;
, ii) tensile strength from about 5 to about 500 psi according to ASTM D412; and
iii) elongation from about 50% to about 800% according to ASTM D412;
wherein said gel pad is positioned directly between the energy source and the living subject;
c) an ultrasonic energy detector; and
d) associated hardware and software for detecting, calculating and displaying a readout of the measured rate values.
